Dado um integrante (exceto bool) ou T tipo de enumeração, fornece a type membro typedef que é o tipo inteiro sem sinal correspondente a T, com o mesmo CV-eliminatórias.
Original:
Given an integral (except bool) or enumeration type T, provides the member typedef type which is the unsigned integer type corresponding to T, with the same cv-qualifiers.

Exemplo
#include <iostream> #include <type_traits> int main() { typedef std::make_unsigned<char>::type char_type; typedef std::make_unsigned<int>::type int_type; typedef std::make_unsigned<volatile long>::type long_type; bool ok1 = std::is_same<char_type, unsigned char>::value; bool ok2 = std::is_same<int_type, unsigned int>::value; bool ok3 = std::is_same<long_type, volatile unsigned long>::value; std::cout << std::boolalpha << "char_type is 'unsigned char'? : " << ok1 << '\n' << "int_type is 'unsigned int'? : " << ok2 << '\n' << "long_type is 'volatile unsigned long'? : " << ok3 << '\n'; }
Saída:
char_type is 'unsigned char'? : true int_type is 'unsigned int'? : true long_type is 'volatile unsigned long'? : true
